@Dan M: the features showcased in this CTP, including enums support, have been rolled into EF5. There is a walkthrough on how to use enums in EF5 here: msdn.microsoft.com/.../hh859576. In fact, when using Code First you should be able to add a property of an enum type and start working with it, but you will need EF5 and .NET 4.5 (currently in beta).

Hope this helps.

It's now May 1, and there still doesn't seem to be a blog post on using enums with Code First. Just putting a public automatic property of type SomeEnum on an entity doesn't seem to work. No column gets created for that property in the database table. Do I need an attribute or something? If you don't have time to write a full blog post, could you at least reply with a simple example? Thanks.

@Stephen: OData currently does not support enums. You will get an exception if you try to use an enum property on your entity

@Jordan: enums are only "CSpace feature" - it means that in the database you will have just a regular column e.g. of int type whose values are cast to the enum type you use in your C#/VB.NET program during materialization.

@Jordan, Niels: A new blog post on enums will be published shortly - it should address your concerns

@dj_kyron: Unfortunately nested types (including enums) are not supported by EF at the moment

@Shimmy: Unfortunately there are no plans for adding support for enums to EF1 and EF4 however .NET Framwork 4.5 is an "in-place" update so EF4 will be replaced with EF vNext when you move to .NET Framework 4.5 and you will be able to take advantage of new features.

Any workaround for previous versions?

My situation: Silverlight RIA, I wanna be able to see the enum property only, plus LINQing against it.

Can we use nested enums defined elsewhere in our code?

I am using Code First and really need this feature. Is there any progress relating writing the mentioned post?

I am looking forward to a post/demo from someone, who can describe how to implement Enums in Code First

I am surprised no one at Ado blog has posted a working sample solution with enum support! It would take 10 minutes and really really help users debug.

Can someone post sample code / database using entities that have enums?

I can't for the life of me get the enums to show up in the database and I would love to compare my config files, sql connections, included references, etc.. to a working sample project.

Does OData support the addition of Enums? What happens to my WCF Data Services endpoint if I use enums?
